Whilst the Armstrong Siddeley Car Club has successfully catered for many years to keep the remaining cars on the road The Armstrong Siddeley Heritage Trust’s prime role is to provide for posterity and the enjoyment of future generations the means and organisation to safeguard the names, records and products of all the companies that came under the direction of John Siddeley.

John Siddeleys involvement in transport preceded the advent of the motor cars with bicycles and tubular tyres progressing to build Peugeot inspired motor cars, continuing with Wolseley-Siddeley cars then onto Siddeley-Deasy motors. Whilst at the helm of Siddeley-Deasy he became involved with Aero-Engine production and finally the manufacture and design of aircraft.

After the first world war, John realised that he needed the security of a much larger manufacturing organisation to survive the overproduction that the war had created. To this end, he engineered the creation of Armstrong Siddeley Motors from a merger of Siddeley-Deasy and Armstrong Whitworth. Once this new organisation was up and running he persuaded the parent company that there was a future in the aircraft industry and caused the Armstrong Whitworth Aircraft company to be brought back into the business.
